variableExpansion
boolean variableExpansion
Indicates that the variable expansion should be performed on this proeprty.The configuration mechanism supports the Ant/Maven like
variable expansion
in the configuration XML out of the box. Normally this happens transparently to objects in modules, hence this property is set to true by default.However, in a rare circumstance you might want to get values injected before the variables are expanded, in which case you can set this property to false to indicate so. Note that such property must be of type
String
(or its collection/array.)Also note the inhabitants can always access the XML infoset by talking to
Dom
directly.- Default:
- true
